Claw couplings for general use and process industry

The standard claw distance is 42 mm. To connect, the couplings must be pressed firmly together and rotated 45 degrees to achieve a proper seal. DIN 3489 is a commonly used standard, while DIN 3238 is applied in situations that require higher safety against unintentional disconnection.

These claw couplings do not comply with the ISO 4414 / health and safety requirement to vent hoses before disconnection.
